Damper

Abstract

A damper has a shell with a cavity. A rotating shaft is rotatably inserted into the cavity of the shell, the portion of the rotating shaft located in the cavity is provided with external thread; a guiding sleeve with internal thread can move along axially reciprocatingly to attach to the shell cavity, and the internal thread and the male thread of the rotating shaft are screwed together; A guiding structure is provided in the shell cavity. The guiding sleeve is engaged or disengaged with the guiding structure by axial movement, and when the two are disengaged, the guiding sleeve can rotate with the rotating shaft. The guiding sleeve is provided with a one-way valve passage. The one-way valve passage opens when the guiding sleeve is axially disengaged with the guiding structure. When the guiding sleeve moves axially in the reverse direction, the one-way valve passage is closed.

Description

TECHNICAL FIELD[0001]The present invention relates to a rotating rotating shaft, and more particularly to a damper capable of slowly falling after a rapid falling of a pivoting member.BACKGROUND TECHNIQUE[0002]Toilet is closely related to people's lives, people use the toilet, it is most frequent that the toilet lid is opened or closed. In the traditional toilet, the toilet lid and the toilet seat are mostly connected through an unhindered hinge, the advantage is that the toilet lid can be flipped quickly, the disadvantage is that when the toilet lid closed the toilet lid easily collide with the toilet seat, which not only exist noise pollution, but also the toilet lids are also prone to wear. For this reason, the damper is generally used to connect the toilet lid and the toilet seat to make the toilet lid closure can be landed slowly. However, the damper used in the prior art has a long damping time to close the toilet lid, the closing process is too slow, it is difficult to meet t...

AI Technical Summary

Benefits of technology

The system reduces the closing time of the toilet lid, prevents collisions, and effectively manages the descent speed, accommodating lighter lids while maintaining quiet operation and supporting heavier lids.

Problems solved by technology

In the traditional toilet, the toilet lid and the toilet seat are mostly connected through an unhindered hinge, the advantage is that the toilet lid can be flipped quickly, the disadvantage is that when the toilet lid closed the toilet lid easily collide with the toilet seat, which not only exist noise pollution, but also the toilet lids are also prone to wear.

However, the damper used in the prior art has a long damping time to close the toilet lid, the closing process is too slow, it is difficult to meet the user's needs.

In particular, for some lighter toilet lid, due to the damper damping force is large, the toilet lid is more difficult to land.
